请问为何import org.apache.log4j.Logger; 会报错

Question

我已经在maven依赖中引入了log4j-1.2.14这个包 但引入logger还是会报错，请问这是为什么？

也配置log4j.properties文件了：

log4j.rootLogger=INFO, stdout, DAILY_INFO

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern= %d %-4r [%t] (%F:%L) %-5p %c%x - %m%n

###simple info
log4j.appender.DAILY_INFO=org.apache.log4j.DailyRollingFileAppender
log4j.appender.DAILY_INFO.File=logs/agent-service.log
log4j.appender.DAILY_INFO.Append=true
log4j.appender.DAILY_INFO.DatePattern='.'yyyy-MM-dd
log4j.appender.DAILY_INFO.layout=org.apache.log4j.PatternLayout
log4j.appender.DAILY_INFO.layout.ConversionPattern=%d %-4r [%t] (%F:%L) %-5p %c%x - %m%n

目测只是eclipse卡了而已，试一下全选、剪切、保存、粘贴、保存试试
